通过jQuery选择类的第一个实例而不是嵌套实例 [英] Selecting first instance of class but not nested instances via jQuery

问题描述

给定以下假设标记:

<ul class="monkey">
    <li>
        <p class="horse"></p>
        <p class="cow"></p>
    </li>
</ul>

<dl class="monkey">
    <dt class="horse"></dt>
    <dd class="cow">
        <dl>
            <dt></dt>
            <dd></dd>
        </dl>
        <dl class="monkey">
            <dt class="horse"></dt>
            <dd class="cow"></dd>
        </dl>
    </dd>
</dl>

我希望能够在每个猴子类中获得马和牛类的第一级".但我不想要 NESTED 马和牛类.

I want to be able to grab the 'first level' of horse and cow classes within each monkey class. But I don't want the NESTED horse and cow classes.

我从 .children 开始，但这不适用于 UL 示例，因为它们不是 .monkey 的直接子代.

I started with .children, but that won't work with the UL example as they aren't direct children of .monkey.

我可以使用 find: $('.monkey').find('.horse, .cow') 但它返回所有实例，包括嵌套的实例.

I can use find: $('.monkey').find('.horse, .cow') but that returns all instances, including the nested ones.

我可以过滤查找: $('.monkey').find('.horse, .cow').not('.cow .horse, .cow .cow') 但这会阻止我选择嵌套实例在第二个函数调用中.

I can filter the find: $('.monkey').find('.horse, .cow').not('.cow .horse, .cow .cow') but that prevents me from selecting nested instances on a second function call.

所以......我想我正在寻找的是'找到这个后代的第一个级别"'.我可能会用一些循环逻辑来做到这一点，但想知道是否有一个选择器和/或一些选择器组合可以实现该逻辑.

So...I guess what I'm looking for is 'find first "level" of this descendant'. I could likely do this with some looping logic, but was wondering if there is a selector and/or some combo of selectors that would achieve that logic.

更新:

这是我最后的结果:

$('.monkey')
    .children('.cow')
        ...do something...
    .end()
    .children('li')
        .children('.cow')
            ...do something...
        .end()
    .end()

看起来冗长/笨拙但似乎有效.

Seems verbose/hacky but seems to work.

推荐答案

使用子元素，因为它为您提供直接的子元素.

Use the children, as it give you the immediate child elements.

$(".monkey").children(".horse, .cow, li > .horse, li > .cow")

已编辑

$(".monkey, .monkey > li").children(".horse, .cow")
